The service is not available in August, when the Library is closed to the general public.

The reproduction of texts is done in compliance with current copyright law and texts will preferably be delivered in electronic format. The Library does not supply texts that are available for free from parliamentary or other websites.

- Public authorities and institutions (constitutional bodies, judicial authorities, central and local governments, libraries, etc..) may, for institutional purposes and at no charge, ask the Service to carry out research into legislative collections and parliamentary documents, comparative and EU law, and into doctrines in the areas of discipline covered by the Library.

- The delivery of texts to individuals is restricted to parliamentary publications and to those publications that are not available in other libraries, and is a facility provided only for people not resident in Rome. Reproduction of texts is free for the first 50 pages; a charge of €0.05 per page or per scan is applied thereafter. If the library already has the texts in electronic format, they are provided at no charge.
